我在Xcode 9工作。代码运行良好,但当我在Xcode 10中使用相同的代码时,就会出现编译时错误。

这是错误:

1.  While emitting SIL for 'fetchConsumerRecommendations(completionHandler:failureHandler:)' at /Users/shahezad/Desktop/Newcode/foodkonnectconsumer-ios/Food/FirebaseManager.swift:2578:5
2.  While silgen emitFunction SIL function "@$S4Food15FirebaseManagerC28fetchConsumerRecommendations17completionHandler07failureH0yySaySSGc_ys5Error_pSgctFZ".

                if (documentSnapshot?.exists)!{

                    print("Consumer Recommendations - \(describing: documentSnapshot?.data())")

                    let dictOnboarding:NSDictionary = (documentSnapshot?.data())! as NSDictionary

                    print("\(dictOnboarding.allKeys)")

                    completionHandler(dictOnboarding.allKeys as! [String])

                }
                else{


                    completionHandler([])

                }

            }
            else{

                failureHandler(error)

            }


        }"
error: Segmentation fault: 11

我不知道这是代码的问题。
